APPARATUS FOR DISTRIBUTING COLOR.

SPECIFICATION forming part of Letters Ifatent No. 609,010, dated August16, 1898. Application filed April 2'7, 1897. Serial No. 684,090. (Nomodel.)

To all whom it may concern.-

Be it known that I, CHESTER COMSTOCK, a citizen of the United States,residing in New York, (Brooklyn,) in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Apparatusfor Distributing Ornalnenting or Enameling Material, of which thefollowing is a specification.

This invention relates to apparatus for applying or distributingornamenting or enameling material on surfaces or ware.

The object of theinvention is to provide a simple and efficientapparatus of this character for applying or distributing ornamenting orenameling material for the purpose of mottling, clouding, shading,marking, or ornamenting ware or other surfaces having a vitrified orother coating thereon.

In the drawings accompanying and forming part of this specification,Figure 1 is a side elevation of one form of this apparatus, with partsthereof broken away and in section and illustrating an article inposition to be treated with ornamenting material applied by means ofthismechanism. Fig. 2 is a top view there of. Fig. 3 is a detail sectionalview taken in line a a, Fig. 2 and Fig. 4 is also a detail sectionalView taken in line b b, Fig. 2.

Similar characters of reference designate like parts in all the figuresof the drawings.

In the manufacture of enameled ware it is now deemed preferable and to acertain ex tent necessary, in order to produce salable articles, toprovide such ware with an ornamented or decorated surface, theornamentations thereof, which in some species of this ware are calledmottlings, being obtained by various processes. Among others is that inwhich a metallic salt is applied to a previously-dried and unfusedenamel coating, and also that in which a second contrasting enamelcoating is applied in a fluid condition to a previouslyapplied enamelcoating,whereby enameled articles having beautiful and highlyornamentalappearances can be obtained, such ornamentations depending upon theornamenting material used and the manner of applying the same, and forthe purpose of applying such ornamenting material I have provided animproved apparatus.

This apparatus in one preferred form thereof heroin shown and describedcomprises a suitable supporting frame or framework, (designatedgenerally by R) which may be of any desired construction adapted tosupport the mechanism vherein shown and described. Supported on thisframework is some suitable means for holding the ornamenting material,shown herein as areceptacle 10, removably secured to said framework. Itwill be understood that this receptacle may be constructed of anymaterial adapted for the purpose and of any desired size and shape.

For the purpose of carrying or conducting the ornamenting material fromthe receptacle suitable conduit means is provided and which may besupported in any desired manner, with one part thereof in communicationwith the ornamenting material in the receptacle, while the dischargeorifice or mouth thereof is in position to permit such material to bedistributed or applied on the article to be decorated, and inthepreferred construction thereof this conduit preferably comprehends anon-corrosive tube 12, preferably of glass, whereby corrosion of thesame, especially at its dischargemouth', as would be the case with anordinary metal tube, by the ornamenting material is prevented. Whilethis tube may be supported to extend over the upper edge of the,receptacle when an uncovered vessel is'used, it is shown hereinprojecting through an aperture or opening 13 in the side wall thereofand removably and adjustably held in position by suitable packing 14,through which said tube projects, this packing being preferably held bya spout or tubular protuberance 14E, fixed on. the receptacle. By

having this tube adjustable its position relative to the discharge endof the compressedfiuid conduit can be regulated. This conduittube is soformed or shaped that its inner end preferably communicates with theornamenting material adjacent to the bottomof the receptacle, wherebyall appreciable amount of such material can be withdrawn from thereceptacle before the refilling thereof becomes necessary.

Adjacent to the discharge orifice' 15 of this conduit-tube the internaldiameter thereof is preferably somewhat less than that of the majorportion of said tube, such discharge end being so curved or constructedthat the ornamenting material will have no tendency to work its wayrearwardly on the under side of the tube, thereby to form in drops anddrip on the article being treated, and, if desired, the discharge endmay be cut away at an angle, to thereby permit the ornamenting materialto be more easily carried downward and distributed.

In order to draw the ornamenting material from the receptacle 10 throughthis conduit 12 and then distribute the same on the surface or articleto be decorated, a suitable instrumentality is provided, which in theform shown comprises a fluid or air forcing apparatus embodying anair-conduit 16 and suitable means for forcing a volume of compressedfiuid or air therethrough, and which in the construction shownpreferably comprehends a blower 17 ,connected in any desired manner, asby a belt 18, with suitable power. (Not shown.) This air-conduit 16,such as a tube or pipe, is supported in position in any desired mannerto have its discharge mouth or orifice 26 adjacent to thedischarge-mouth of the conduit 12; but, as illustrated herein, it issupported on the receptacle by a suitable clamp device, which in itspreferred form comprises afurcated member 20,carryinga clampscrew 21.One part of this clamping member 20 engages the inner face of thereceptacle-wall, while a complementary separate clamping member 22engages the outer face of said wall, being clamped thereon by theclamp-screw 21, whereby the compressed-air conduit may be adjusted onthe receptacle to bring its discharge-orifice into position adj acent tothe discharge-orifice of the material conduit. On the clamping member 20the compressed-air conduit is shown removably supported, preferably withits discharge end diverging from the receptacle, thereby to permit thebetter adjustment in the present structure of the material-cond uittoward and from said compressed-air conduit. This compressed-air conduitis connected with the blower 17 in any desired way, such as by flexibletubing 23.

For the purpose of regulating the volume of air or other fluid passingthrough the conduit 16 suitable regulating means is provided, such as acock 24, shown carried by such conduit, whereby in manipulating the samethe compressed air may be partially or entirely cut off. This conduit 16is illustrated provided at its working end with a downwardlyextendingpreferably gradually-converging spout 25, forming a discharge orifice ormouth 26, shown of larger diameter than the orifice of thematerial-conduit, and in position in this structure of apparatusdirectly above the discharge-orifice 15 of the conduit 12, whereby thedischarge-orifices 15 and 26 are in such positions relatively to eachother that the Volume of the compressed air is directed across thematerial-conduit orifice 15 and over and around the same, whereby itwill not only draw a portion of the ornamenting material from thereceptacle through its conduit 12, but will also completely envelop andencircle the same, such ornamenting material being thus carried in thecenter of such volume of ejected air, and thereby distributed in theform of a spray directly on the article to be decorated, and which spraywill be in the nature of drops or globules, which may be so fine as tobe practically imperceptible to the eye or may be larger, as desired,the size of such drops or globules being determined by the character andsize of the article to be decorated and the manner in which the same isto be ornamented. Variation in the size of these drops or globules maybe obtained by varying the size of the discharge-orifice 15 of theconduit 12, which may be done in any desired manner-as, for instance, bymeans of interchangeable conduits and by regulating the volume ofcompressed air forced through the air-conduit 16.

It will be understood that any ornamenting material which can bedistributed in the manner set forth may be used with this apparatus.

In the distribution of the ornamenting ma terial on the article which isheld in the path of the same by the operator more or less of suchmaterial drops off, and hence in order to guard against waste a suitablecatch-receptacle 27 is provided and supported by the framework inposition beneath the conduit discharge-orifices 15 and 26, andpreferablyhas a converging bottom 28, whereby the superfiuous materialis caught and waste thereof prevented.

In the operation of this improved apparatus when it is desired toornament or deco-' rate an article or vessel the operator manipulatesthe same below, in this construction of apparatus, thematerial-discharge orifice 15, the regulating device having previouslybeen adjusted, whereupon the volume of compressed air or fluid forcedthrough the conduit 26 draws the ornamenting material from thereceptacle and enwraps the same and distributes it in the form of aspray comprising large or small drops or globules, as the case may be,on the article at any desired stage in the process of enamelingthe same,whereby a highly and beautifully ornamented appearance is obtained,varying according to the ornamenting material used, the regulation ofthe apparatus, and the manipulation of the article to be decorated.

Having thus described my invention, I claim- 1. In an ornamentingapparatus, the combination of a receptacle for holding ornamentingmaterial; a fluid-conduit; a removable ornamenting-material conduit inposition to convey material from said receptacle; the discharge endthereof having a concaved or curved under face thereby to prevent theornamenting material from working its way rearwardly and forming indrops on the under side of said conduit; said conduits being in suchposition, relatively to each other, that the fluid from thefluid-conduit will draw the and having its discharge end divergingtherefrom and provided with a depending spout having a relatively largedischarge-orifice for the discharge of a relatively large volume offluid; a material-conduit adjustably and removably carried directly bysaid receptacle, and having its discharge end curved downwardly in thedirection of the depending spout, and provided with an orifice ofrelatively small diameter as compared with the orifice of thefluid-conduit, and in position below and underneath thedischarge-orifice of said spout, whereby the volume of fluid will crossthe material-discharge orifice and pass over and around the same,thereby to draw the ornamenting material through its conduit andcompletely envelop and force the same in a direction at right angles tothe normal level of said ornamenting material in said receptacle and inthe form of a spray on the article to be treated.
